Porsche has officially ended production of all current diesel vehicles in the face of changing consumer demand and upcoming stricter emissions tests.

In a move that a Porsche spokesman said mirrors the “cultural shift” of the brand's customers, the German manufacturer has discontinued its only two current diesel models, the Macan S Diesel and Panamera 4S Diesel (pictured below), just nine years after its first oil-burner hit the market.

The original Cayenne was the first Porsche to offer diesel power back in 2009. Porsche was originally reported to be launching the new Cayenne with only petrol and petrol-electric hybrid powertrains, but has now announced that a diesel variant is on the way.

In an official statement, Porsche said that the Macan S Diesel, the only such version of the brand’s Range Rover Velar rival, has been “taken out of the production programme” as buyer demand moves towards petrol and hybrid versions.

The brand revealed that the diesel’s removal was also linked to “another software update” that has been subject to an “ongoing consultation with the authorities”. While not directly confirming it, this suggests that like with BMW and its F80 M3, Porsche has decided against re-engineering the Macan S Diesel to conform to the new Worldwide Harmonised Light Vehicles Test Procedure (WLTP) standards.

The same justification was given for the demise of the Panamera 4S Diesel, which was removed from Porsche’s ranks during the luxury car's range update at the start of the year.

Porsche said the change was linked to falling demand for the variant, which accounted for 15% of the Panamera’s 11,000 global sales in 2017. Petrol versions accounted for 35%, while the Panamera 4 E-Hybrid accounted for 50%.

An inside source told Autocar that the current lack of diesel cars in its range doesn't "mean Porsche has decided to stop all diesel models" forever. But Porsche boss Oliver Blume revealed to Autocar last year that “diesel is not so important for Porsche”, adding that diesel sales made up just 15% of Porsche’s total worldwide sales, mostly in Europe.

Porsche revealed the following statement on its diesel plans: "Traditionally, diesel engines have played a subordinate role at Porsche – the company does not develop or build diesel engines itself. Currently, the demand for diesel models is falling, whereas interest in hybrid and petrol models is increasing significantly. For example, the ratio for hybrid versions of the new Panamera in Europe is around 60 percent."

"In light of these facts Porsche has adapted its production planning. This decision means that Porsche currently does not offer any vehicles with diesel engines. However, it does not mean a diesel exit at Porsche. As announced, the new Cayenne is set to feature a diesel powertrain. The exact time of the market launch is not yet clear."

Unlike its petrol engines, Porsche never developed its own diesel powerplants, instead sourcing them from elsewhere within the Volkswagen Group. Porsche halted investment in diesel last year, shifting much of its R&D focus to electrification.

Our Verdict

Porsche's 'junior Cayenne' promises and delivers on its dynamic and performance prowess to be be the most sporting SUV of its size. However, the market has changed with the newrivals threatening to challenge the Macan's crown, so does it have the stomach for a fight?

Other reports have suggested that there's a lot more to this story than "demand has fallen so we've stopped offering diesels".

Supposedly the German regulators are still refusing to accept Audi's "fix" for the cheating diesel engines used in the Macan, and already rejected the latest Cayenne diesel engine. If Porsche can't get regulator approval to sell its cars, they don't really have any choice.

And it's still possible Porsche may have to buy back every Macan diesel ever sold in Europe, which is why the engine has been withdrawn before the end of the model cycle and new testing protocols. Fewer cars built = fewer to have to buy back again...

Not really reflected on the used market - I've been trying to sell a 2012 Cayenne Turbo in the trade and when I've been speaking to specialist dealers the answer I get is that buyers are all looking for the diesel versions due to better fuel economy, and the petrols take ages to sell...
